The RAM passes Memtest86+ v4.0. I know it is strange. - Henrik

It might have to be trial-and-error then to work out which stick(s) is/are faulty, but you might want to give memtest86 a look.

Subject: RE: PowerEdge 1950 ECC question... I cannot get the node to startup to the point where OMSA runs. It freezes on startup with the bad RAM. - Henrik -----Original Message----- From: Ryan Miller [mailto:rmil...@smartertravelmedia.com] Sent: Wednesday, February 03, 2010 10:19 AM To: Henrik Schmiediche; linux-powere...@lists.us.dell.com Subject: RE: PowerEdge 1950 ECC question... Are you running OMSA? It usually is able to pinpoint which stick is the cause of single bit errors. It can be helpful to stress the RAM with some heavy compiles/DMA to make the bad stick throw an SBE sooner. > -----Original Message----- > From: linux-poweredge-boun...@dell.com [mailto:linux-poweredge- > boun...@dell.com] On Behalf Of Henrik Schmiediche > Sent: Wednesday, February 03, 2010 11:09 AM > To: linux-powere...@lists.us.dell.com > Subject: PowerEdge 1950 ECC question... > > Hello, > Is it possible to turn ECC off on the PowerEdge 1950?
